Pros

None anyone that wants to work there fairly

Cons

I want to leave this as a warning for people considering applying to 3M. From what I witnessed, the work environment raised serious concerns. The policies did not seem to be applied consistently, and there appeared to be favoritism in how situations were handled. In one situation involving chemical work, a trainer was terminated after a trainee made a mistake, even though similar situations in the past reportedly did not lead to trainers being fired. The way management and HR handled the situation left employees feeling like their concerns were not being fairly addressed. Anyone considering working here should make sure they fully understand the expectations and workplace culture before accepting a position.
